RULE AND RULING DEVICE.

SPECIFICATION forming part of Letters Patent No. 530,043, dated November27, 1894.

Application filed July 25, 1894. Serial No. 518,532. (No model.)

T0 on whom it may concern.-

Be it known that I, GEORGE HARVEY, a subject of the Queen of GreatBritain, and a resident of Winnipeg, in the county of Selkirk andProvince of Manitoba, Canada, have invented certain new and usefulImprovements in Rules and Ruling Devices; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled -in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, andto letters of reference marked :hereon, which form a part of thisspecifica- Figure 1 of the drawings is a perspective view of theinvention. Fig. 2 is a plan view of invention showing two handles. Fig.3 is a cross-section showing blotting paper.

This invention has relation to certain new and useful improvements inruling devices, the object being to provide a simple, strong, andconvenient device of this character, capable of being used much morerapidly than an ordinary rule, and especially designed for use in rulingpaper, it being. provided with means for carrying the rule above thepaper and out of the way of the ink.

With this object in View the invention con-' sists in the novelconstruction and combination of parts, all as hereinafter described, andpointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates theframe of the device, consisting of a light bar of metal, either circularor angular in cross-section, and having its end portions bent atsubstantially right angles, as indicated at a, a. Secured to said endportions and lying parallel with the body of the frame, is the rule B,which preferably consists of a thin bar of metal of L form in crosssection. This form is preferred for the reason that it is stronger, butI do not wish to limit myself thereto, as other forms will suffice.Journaled between the arms a, a, of the frame, and parallel with therule, is an elongated roller 0, which is of such diameter that it willhold the frame and rule sufficiently above the paper to avoid theircoming in contact with the ink. Atthe cen- 5o ter, the frame and ruleare preferably connected by an upwardly curved brace-arm D.

E designates a handle attached to the body of the frame at the centralportion thereof.

In some devices I may employ two such handles placed near each other, asshown in Fig.

2, so that the device may be held firmly without danger of its slipping.

F designates a gage which is placed at one side of the rule in orderthat in ruling lines they may be made at equal distances apart. Thisgage I have shown as consisting of a small piece of metal pivoted to thehorizontal flange of the rule near one end thereof, and having a beveledinner end which permits the gage when not in use to be turned back ontothe flange and out of the way, and which, when the gage is in use,engages with the vertical flange of.the rule and holds it extended.

In Fig. 3 I have shown the roller 0 as having a wrapping of blottingpaper, this feature adding to the value of the device when used forruling paper.

The rule may be marked with any desired scale.

The roller 0, in addition to its office of bolding the. frame and ruleout of contact with the paper, also enables the device to be morerapidly and readily moved from point to point over a surface.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein described improved ruling device, comprising the framecomposed of the bar A having its end portions bent at right anglesthereto, a rule B secured to said end portions, an elongated rollerjournaled in said end portions between the bar and rule, 0 and paralleltherewith, and a gage device carried by said rule, substantially asspecified.

2. The herein described improved ruling device, comprising a bar havingits end portions bent at substantially right angles 5 thereto, the ruleB secured to said end portions and consisting of a thin bar of metal ofL-shape in cross-section, the upwardly curved brace-arm D connectingsaid bar and rule,

one or more handles attached to the central portion of said bar, and agage device F, consisting of a small piece of metal pivoted to thehorizontal flange of the rule, and having a beveled inner end whichpermits said gage when not in use to be turned back onto the flange andout of the Way, and. which, when the gage is in use, engages with thevertical flange of the rule, substantially as specified. 10

In testimony WhereofI affix my signature in presence of two witnesses.

GEORGE HARVEY.
